FIG. 1 is a view illustrating an electronic device, according to an embodiment.

Referring to FIG. 1 , an electronic device 100 may construct a network 200 together with at least one external device 300 (or an external server). The electronic device 100 may transmit data or a signal associated with function use to the external device 300 or may receive the data or the signal from the external device 300, by accessing the network 200. According to various embodiments, the network 200 may include a computer network (e.g., a local area network (LAN) or a wired area network (WAN)), the Internet, or a telephone network.

According to an embodiment, the electronic device 100 may include a camera module 110, a memory 120, a display 130, a communication interface 140, a processor 150, and a housing 160. According to various embodiments, the electronic device 100 may not include at least one of the above-described components or may further include any other component(s). For example, the electronic device 100 may further include a power supply device (e.g., a battery) to supply electrical energy to the components, a sensor module (e.g., a proximity sensor, an acceleration sensor, a fingerprint sensor, or an iris sensor) to sense various pieces of information, or a speaker module to output a sound acquired from an inside or an outside.

The housing 160 may receive at least some of the components (e.g., the memory 120, the communication interface 140, or the processor 150) of electronic device 100 described above, or may support the mounting of the at least some of the components. The housing 160 may include a bottom surface, at least one side surface extending at a specified angle (e.g., substantially perpendicularly) from an edge of the bottom surface at a specified angle, and a top surface opposite to the bottom surface. At least a portion of the top surface may be open. For example, a region having a specified area from the center of the top surface may be open, so the housing 160 may include an inner space having at least a partial region that is open. According to various embodiments, the housing 160 may include, in at least a partial region thereof, at least one opening (not illustrated) for exposing a functional key (e.g., a power key or a volume control key) associated with the use of the electronic device 100.

The camera module 110 may capture an image (e.g., a still image or a video, etc.) of the surrounding region of the electronic device 100 based on a specified angle of view. In one embodiment, the camera module 110 may be disposed in a partial front region of the electronic device 100 to have an angle of view in a first direction (e.g., forward of the electronic device 100). For example, the camera module 110 is disposed on a front region of the display 130 having at least a portion exposed out of the housing 160. In this case, the camera module 110 may be disposed at an edge of the display 130 such that the visibility of content displayed on the display 130 is not interrupted. In one embodiment, the camera module 110 may include a first camera and a second camera. Any one of the first camera and the second camera may include a 3D depth camera. The angles of view of the first camera and the second camera may be similar to each other or may at least partially overlap with each other. In various embodiments, a plurality of camera modules 110 may be provided to have angles of view in the first direction and a second direction (e.g., rearward of the electronic device 100) opposite to the first direction, and may be disposed on front and rear surfaces of the display 130.

The memory 120 may store a command or data associated to another component of the electronic device 100 or the external device 300 that interacts with the electronic device 100. For example, the memory 120 may store an image captured by the camera module 110 or data based on content received from the external device 300. In one embodiment, the memory 120 may include a content (e.g., a video) analysis database. The content analysis database may be used, for example, to detect an object specified for any content. In this regard, the content analysis database may include relevant information (e.g., the shape, feature, or contour of the object) of the specified object.

The memory 120 may include at least one program associated with the function use of the electronic device 100. The program may include, for example, an application program (e.g., a call program), a kernel, a middleware or an application programming interface (API). At least a portion of the kernel, the middleware, or the API may be called as an operating system (OS). According to various embodiments, the memory 120 may include at least one of a volatile memory (e.g., a dynamic random access memory (DRAM), a static RAM (SRAM), or a synchronous DRAM (SDRAM)), a nonvolatile memory (e.g., one time programmable read only memory (OTPROM), a programmable ROM (PROM), an erasable and programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM) or the like), a mask ROM, a flash ROM, or a flash memory.

The display 130 may display various screens corresponding to user control or specified scheduling information. For example, the display 130 may display an image (e.g., a still image or a video) captured by the camera module 110 or content received from the external device 300. According to an embodiment, the display 130 may display multiple pieces of content (e.g., video) on a single screen. For example, the display 130 may display first content (e.g., a first image), which is received from the external device 300, in a specified first size on a portion of the screen region and display second content (e.g., a second image), which is produced by the camera module 110, in a second size on a remaining portion of the screen region, when specific program (e.g., video telephone program) is executed. According to various embodiments, the first size and the second size for displaying multiple pieces of content may be equal to or approximate to each other. Alternatively, the display 130 may display the first content in a specified size (e.g., a full screen size) on the screen region and may display second content, which overlaps with at least a partial region of the first content, produced by the camera module 110.

According to an embodiment, the display 130 may include a transparent display that is able to control a specified screen element (e.g., light transmittance (or transparency), color, or saturation) under the control of the processor 150. In this regard, at least one component associated with the function operation of the display 130 (or included as the component of the display 130) may be formed of a transparent material. For example, when the display 130 is implemented with a touch screen, at least one electrode layer associated with the detection of a user input (e.g., a touch, proximity, drag, or hovering) may include a transparent conductive film (e.g., Indium Tin Oxide (ITO)). In addition, a control circuit to calculate the coordinates, in which the user input is made, or the duration of the user input based on the variation in the physical quantity (e.g., a voltage or a capacitance) of the at least one electrode layer may be disposed, for example, in the internal space of the housing 160 while avoiding the display 130.

The communication interface 140 (or communication module) may support communication between the electronic device 100 and the external device 300. For example, the communication interface 140 may support the communication between the electronic device 100 and the external device 300 by accessing the network 200 based on wired communication or wireless communication. According to various embodiments, the wireless communication may use, for example, at least one of long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), or global system for mobile communications (GSM), and the like as a cellular communication protocol. The wireless communication may include short range communication, such as wireless fidelity (Wi-Fi), Bluetooth, near field communication (NEC), or magnetic stripe transmission (MST).

The processor 150 is electrically or operatively connected with other components of the electronic device 100 to perform a control, a communication computation, or data processing for the components. For example, the processor 150 may perform setting of image data on at least one image (e.g., a still image or video) captured based on the camera module 110. The setting of the image data may be associated with the control of a screen element (e.g., light transmittance (or transparency), color, or saturation) for at least a partial region of the display 130 when the image is displayed on the display 130 (e.g., a transparent display). For example, when the setting of the image data on a specific object of at least one object included in an image is performed by the processor 150, a region, which corresponds to the specified object on the display 130, may be controlled and displayed based on a screen element (e.g., light transmittance (or transparency) color, or saturation) based on the setting of the image data.

According to an embodiment, the processor 150 may perform the setting of the image data based on any one of a plurality of images captured by the first camera and the second camera of the camera module 110. In addition, the processor 150 may perform the setting of the image data based on the combination of the plurality of images. The processor 150 may transmit data on an image, which is subject to the setting of the image data, to the external device 300 by controlling the function operation of the communication interface 140.

FIG. 2A is a view illustrating a first image, according to an embodiment, FIG. 2B is a view illustrating a second image, according to an embodiment, and FIG. 2C is a view illustrating an image display state on the display, according to an embodiment. The functions or the operations to be described with reference to FIGS. 2A, 2B, and 2C may be associated with a video telephone environment between the electronic device and the external device.

Referring to FIG. 2A, the processor 150 (see FIG. 1 ) may perform image data setting based on a first image 10 captured by the first camera of a camera module 110 (see FIG. 1 ). In this regard, the processor 150 may perform image analysis by obtaining the first image 10 from the camera module 110 or the memory 120 (FIG. 1 ). For example, the processor 150 may detect at least one object (hereinafter, referred to as a “first object”) included in the first image 10 based on image processing such as edge detection filtering, or active contours modeling. According to an embodiment, the processor 150 may extract a specified object (e.g., a human body; hereinafter referred to as a “second object”) of the first object based on a machine learning algorithm (e.g., deep learning). In this operation, the processor 150 may refer to a content analysis database constructed in the memory 120. For example, the processor 150 may identify an object, which is matched at a specified ratio or more with the contour of the second object, of the detected first object, based on the information on the contour (or the shape) of the second object included in the content analysis database and may extract a second object 1 from the first image 10. In addition, the processor 150 may extract at least one feature of the detected first object and may extract the second object 1 from the first image 10, based on the comparison between the at least one feature of the first object and feature point information, which is included in the content analysis database, of the second object.

According to an embodiment, the processor 150 may perform image data setting for a remaining object (hereinafter, referred to as a “third object”) of the at least one first object except for the extracted second object 1. The processor 150 may control the light transmittance of the screen region corresponding to the third object on the display 130 (FIG. 1 ; e.g., a transparent display) to be a specified value, based on the image data setting. For example, the processor 150 may control the screen region of the third object to be transparent on the display 130 by setting an alpha (α) value (e.g., a value associated with the transparency of the image) for image data of the third object to a specified value (e.g., 100 in the range of 1 to 100). In addition, the processor 150 may control the screen region corresponding to the third object to be transparent on the display 130 by setting R, G, and B grayscale values of the image data of the third object to a specified value (e.g., 255).

According to various embodiments, the processor 150 may further control screen elements such as color or saturation as well as the control of the light transparency, based on the image data setting for a specific object or region in the first image 10. For example, the processor 150 may control the output of the display 130 such that a region of the display 130 except for the second object 1 is displayed in specific color, or displayed to be clear or blurred. Hereinafter, the control of the light transparency for a specific screen region of the display 130 will be described as screen element control of the display 130 based on the image data setting by way of example.

Referring to FIG. 2B, the processor 150 may perform image data setting based on a second image 20 captured by the second camera (e.g., a depth camera) of the camera module 110. The second image 20 may include depth information (or distance information based on the second camera) of at least one object included in an image. The depth information may be calculated based on time in which a signal (e.g., infrared signal) transmitted from the second camera is reflected from an object and returns to the second camera. The processor 150 may identify a layer including the object 1 present at less than a specified depth (or distance) on the second image 20 based on the depth information. According to an embodiment, the processor 150 may perform the above-described image data setting with respect to the remaining layer except for the identified layer. For example, the processor 150 may set at least one alpha (α) value to a specified value (100 in the range of 1 to 100) or R, G, and B grayscale values to a specified value (e.g., 255), with respect to image data of at least one object included in the remaining layer.

According to an embodiment, the processor 150 may perform image data setting with respect to the first image 10 and the second image 20 by combining the first image 10 and the second image 20. For example, the processor 150 may extract a specified object (e.g., a human body) from at least one object included in the first image 10 based on the image analysis for the first image 10, and may map the first image 10 to the second image 20. The processor 150 may exclude the depth information from the second image 20 and may identify an object, which is mapped to an object (e.g., a human body) extracted from the first image 10 at an equal ratio or an approximate ratio, and a layer including the object. The processor 150 may perform image data setting (e.g., the setting of an alpha (α) value or the setting of the R, G, and B grayscale values) with respect to remaining layers except for the identified layer. The processor 150 may perform image data setting by clearly determining a region of a specified object (e.g., a human body) included in the image, based on the combination of the first image 10 and the second image 20.

According to an embodiment, the processor 150 may transmit information on the image data setting performed based on any one of the first image 10 or the second image 20 to an external device (300 of FIG. 1 ) together with the data on the first image 10. According to an embodiment, the processor 150 may transmit information on the image data setting, which is performed based on the combination of the first image 10 or the second image 20, to the external device 300 together with the data on the first image 10.

Referring to FIG. 2C, the external device 300 may receive information on image data setting and data on the first image 10 (FIG. 2A) from the electronic device 100 (FIG. 1 ) and may display the first image 10 on a display included in the external device 300. In this regard, the external device 300 may include a transparent display 130 a. According to an embodiment, the information on the image data setting may include image data, the alpha (α) value of which is set to a specified value (e.g., 100 in the range of 1 to 100), on a remaining object (a layer except for a layer including the object 1) of at least one object included in the first image 10 except for the specified object 1 (e.g., the human body of a user of the electronic device 100). In addition, the information of the image data setting may include image data, R, G, and B values of which are set to a specified value (e.g., 255), on the remaining object (or the layer except for the layer including the object 1) except for the specified object 1. Accordingly, a region 2 (or the background region of the specified object 1) except for the specified object 1 of the screen region of the transparent display 130 a provided in the external device 300 to display the first image 10 may be transparently controlled corresponding to the alpha (α) value or the R, G, and B values, and an arbitrary object (e.g., a book) disposed at the rear portion of the transparent display 130 a may be visualized. According to various embodiments, a display object 3 (e.g., an icon) associated with the termination of the video telephone function may be displayed on some region of the transparent display, in relation to the use of the video telephone.

In various embodiments, the user of the electronic device 100 may control, for example, content (e.g., video) transmission setting when operating the video telephone function. For example, the user of the electronic device 100 may control the above-described information on image data setting not to be transmitted to the external device 300 through the user interface associated with content transmission setting or based on system setting of the electronic device 100. In this case, the transparent display 130 a of the external device 300 may display the first image 10 received from the electronic device 100 without change.

In various embodiments, the external device 300 may include a camera that is the same as or corresponds to at least one of a first camera or a second camera (e.g., a depth camera) of the electronic device 100. The external device 300 may perform image data setting which are the same as or similar to image data setting of the electronic device 100 described above, to the image captured by the camera. Accordingly, the electronic device 100 may receive information on the image data setting from the external device 300 and may display the image on the display (130 in FIG. 1 ; e.g., a transparent display) in the form the same as or the form corresponding to the form illustrated in FIG. 3C.

FIG. 3A is a view illustrating a first image, according to another embodiment, FIG. 3B is a view illustrating a second image, according to another embodiment, and FIG. 3C is a view illustrating an image display state on a display, according to another embodiment. In FIGS. 3A, 3B, and 3C, the functions or operations performed by an electronic device or an external device may be similar to or correspond to those described above with reference to FIGS. 2A, 2B, and/or 2C. Hereinafter, the function or operations different from those descried with reference to FIGS. 2A, 2B, and/or 2C will be described.

Referring to FIG. 3A, a processor 150 (see FIG. 1 performs image analysis with respect to a first image 10 captured by a first camera of a camera module 110 (see FIG. 1 ) and may detect at least one object (hereinafter, referred to as a first object) from the first image 10. The processor 150 may extract an object 1 (e.g., a human body; hereinafter, referred to as “second object”), which is specified from the first object, from the content analysis database constructed in a memory 120 (see FIG. 1 ). In one embodiment, the detected first object may include at least one object (hereinafter, referred to as a “third object”) associated to the second object 1. For example, the at least one first object may include a third object positioned forward from the second object 1 on the first image 10 or the third object which is included in an upper layer of a layer including the second object 1 to overlap with the second object. In this case, the processor 150 may determine the third object 4 as at least a portion of the second object 1 by considering the disconnection of at least a portion of the second object 1. The processor 150 may perform an image data setting operation of setting, for example, alpha (α) value to a specified value (e.g., 100 in the range of 1 to 100) or R, G, and B grayscale values to a specified value (e.g., 255), with respect to image data of remaining objects of at least one first object except for the second object 1 and the third object 4.

Referring to FIG. 3B, the processor 150 may obtain depth information (or the information on the distance from the second camera) of at least one object in the second image 20, based on the second image 20 captured by the second camera (e.g., a depth camera) of the camera module 110. In one embodiment, a plurality of objects 1 and 4 having depth values less than a specified depth may be included in the second image 20.

An arbitrary object (e.g., a book) positioned at a rear portion of the transparent display 130 a may be visualized on a remaining portion of the screen region of the transparent display 130 a by controlling the light transparency based on the image data, the alpha (α) value (100 in the range of 1 to 100) or the R, G, and B values (e.g., 255) of which are set to a specified value.

FIG. 4A is a view illustrating a first image, according to another embodiment, FIG. 4B is a view illustrating a second image, according to another embodiment, and FIG. 4C is a view illustrating an image display state on a display, according to another embodiment. In FIGS. 4A, 4B, and 4C, the functions or operations performed by an electronic device or an external device may be similar to or correspond to those described above with reference to FIGS. 2A, 2B, and/or 2C. Hereinafter, the function or operations different from those descried with reference to FIGS. 2A, 2B, and/or 2C will be described.

Referring to FIG. 4A, a processor 150 (see FIG. 1 ) may perform image analysis with respect to a first image 10 captured by a first camera of a camera module 110 (see FIG. 1 ). The processor 150 may detect at least one object (hereinafter, referred to as a first object) from a first image 10 through the image analysis. The processor 150 may extract an object (e.g., a human body; hereinafter, referred to as “second object”), which is specified in the first object, from a content analysis database constructed in the memory 120 (see FIG. 1 ). In an embodiment, the processor 150 may extract a plurality of second objects 1 and 5 from the first object. In this operation, the processor 150 may output a first user interface associated with image data setting for each of the plurality of second objects 1 and 5 which are extracted. The first user interface may include image content for the plurality of second objects 1 and 5 and a control tap to control whether the image data setting is performed with respect to each of the plurality of second objects 1 and 5. The electronic device 100 may control whether the image data setting is performed with respect to the plurality of second objects 1 and 5, based on a user input (e.g., a touch) applied to the control tap. According to an embodiment, when the user controls the plurality of second objects 1 and 5 such that none second object is subject to the image data setting, the processor 150 may perform the image data setting with respect to remaining objects of the first object, which is detected through the image analysis, except for the plurality of second objects 1 and 5.

Referring to FIG. 4B, in an embodiment, the processor 150 may obtain depth information of at least one object in a second image 20, based on the second image 20 captured by a second camera (e.g., a depth camera) of a camera module 110. In this operation, the processor 150 may output the second user interface including, for example, the depth information. The second user interface may include, for example, image content for at least one object included in the second image 20 and depth information corresponding to each object. The user of the electronic device 100 may select at least one object which is to be subject to the image data setting, based on the second user interface. For example, when the user applies a user input (e.g., a touch) onto at least one specific image content (e.g., image content corresponding to the objects 1 and 5) included in the second user interface, the processor 150 may perform image data setting with respect to a remaining layer on the second image 20 except for at least one layer including the relevant object of the specific image content.

Referring to FIG. 4C, the external device 300 may receive information on image data setting and data on the first image (10 of FIG. 3A) from the electronic device (100 of FIG. 1 ) and may display the first image 10 on the transparent display 130 a. The information on the image data setting may include user control information based on the first user interface or the second interface described with reference to FIG. 4A or FIG. 4B. According to the image data setting information, the objects 1 and 5, which are controlled not to be subject to the image data setting by the user of the electronic device 100 or correspond to image contents selected by the user of the electronic device 100, may be displayed on at least a portion of the screen region of the transparent display 130 a of the external device 300. An arbitrary object (e.g., a book), which is positioned at a rear portion of the transparent display 130 a, may be visualized on a remaining portion of the screen region of the transparent display 130 a, due to the light transparency resulting from the alpha (α) value (100 in the range of 1 to 100) or the R, G, and B values (e.g., 255) based on the image data setting.

FIG. 5 is a view illustrating an operating environment of the electronic device, according to an embodiment.

Referring to FIG. 5 , the processor 150 (see FIG. 1 ) of the electronic device 100 may calculate the distance between the electronic device 100 and the user 1 by referring to the first image 10 (see FIG. 2A, 3A, or 4A) and the second image 20 (see FIG. 2B, 3B, or 4B) captured by the camera module 110 (see FIG. 1 ) in real time or at a specified period. For example, the processor 150 extracts a specified object (e.g., a human body) on the first image 10 and obtains depth information of the specified object through the mapping analysis to the second image 20, thereby tracking the variation in the distance between the electronic device 100 and the user 1. Alternatively, the processor 150 may determine whether the user 1 is present within the angle θ of view of the camera module 110 based on the analysis of the first image 10 or the second image 20.

In one embodiment, the processor 150 may control a specified function of the electronic device 100 based on the distance information from the user 1 and the determination of whether the user 1 is present within a specified range (e.g., the range of the angle of view of the camera module 110). For example, the processor 150 may operate or maintain the call function of the electronic device 100 as a video telephone function when the user 1 is present at the specified distance “r” or within the specified range “θ”. When it is not determined that the user 1 is present at less than the specified distance “r” or within the specified range “θ”, the processor 150 may operate or maintain the call function of the electronic device 100 as a voice call function.
